MARTIN CHLADEK, OF SHAMOKIN, PENNSYLVANIA.

TREE-TRIMMING SHEARS.

Specication of Letters Patent.

Application led July 20, 1917. Serial No. 181,722.

To all whom t may concern:

Be it `known that I, MARTIN CHLADEK, a subject of the King of Hungary,resident of Shamokin, county of Snyder and State of Pennsylvania, haveinvented certain new and useful Improvements in Tree-Trimming Shears, ofwhich the following is a specification. This invention relates toimprovements for devices for trimming the boughs, limbs or foliage oftrees, shrubs, and the like, such as are not readily accessible from theground.

The principal object of the invention is to provide means which may beattachedv to commercial shears of a suitable character without in anyWay damaging them, and which 'may be operated by a single individualwith entire ease.

Another obj ect is the shear holding means with a saw holder and meansfor its operation, the attachment being interchangeably engaged witheither shears or saw.

These and other like objects are attained by the novel construction andcombination of parts hereafterdescribed and shown in the accompanyingdrawings, forming a material part of this disclosure, and in whichs-Figure l is a side elevational view of a pair of shears to which theattachment is applied and indicating its operation. Y

Fig. 2 is a similar view showing a different form of shear,

Fig. 3 is a perspective view of the clamp plate by means of which theattachment to the shears is made, and

Fig. 4 is a view of the hook bolt used inA connection therewith.

In Figs. 1 and 2, the shear blades 10 and l1 are pivoted at the centralpoint by the rivet pin l2, so as to cross each other in the ordinarymanner, the shank having eyes `15 and 16 through which the hand oringers of the operator can be inserted when using the shears in theordinary manner.

A plate 18 is adapted to be engaged with the inner side of the shearshank or handle 16, the shank being tightly held between raisedprojections 19 and is further secured to the plate by means of hookbolts 20, pass- Gopiel of this patent may be obtained for live centseach, by addressing the Washington, D. c."

ing through appropriately formed openings 21 in the plate, in theopening so as to hold the shears rigidly. A handle or pole 25 is used tomanipulate the shears, the same having a reduced end engaged by rivets26 to the eX- tension 28 formed with the plate 18.

A block 3() is arranged on the back of the plate 18, carrying a flatspring 31, the free end 32 of which abuts against the inner side of theshank formed with the blade 11, thereby keeping the shears openposition, the block between the spring and the plate being secured bythe stems of the hook bolts and held by the nuts 33.

Formed with the handle 25 are a pair of lugs 35, carrying a pin 36, uponwhich is mounted a pulley 37, over which runs a cord 38, engaged bymeans of a hook 39 or the like to the opposite shear handle, it beingunderstood that the length of the cord 38 is substantially equivalent tothe length of the handle 25, by means of which the apparatus ismaneuvered.

In operation, the handle being grasped by the user, the cord 38 ispulled, closing the shear blades together, opposing the spring 3l, whichimmediately opens the shears when the cut has been made.

The application of the invention is believed to be obvious from theforegoing, taken in connection with the drawings.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The combination with a pair of shears, of a plate, forks formed Von saidplate adjacent the ends thereof and engaging one of the handles of saidshears, said plate having openings therein, hooks carried by the plateand passing through certain of the openings and engaging the same handleof the shears the hooked portion engaging Patented Aug. 13, 1918.
